Flocculation-Coagulation Operations:

on 27/09/2019 No comments

Wastewater contains suspended material, solid particles that can settle on their own, but we can also find very small particles of a colloidal kind with a size between 0.001 and 1 µm. It is not possible to divide these particles by decantation or flotation. Neither we could filter them because they would pass through any filter.

Each of these colloids contains particles stabilised by a series of equivalent charges on their surface, causing two adjacent particles to repel as two magnetic poles repelling each other. This prevents them from agglomerating to settle.

Coagulation is caused by the removal of electrical layers surrounding colloidal particles with the formation of microscopic nuclei. Flocculation consists of an agglomeration of destabilised particles in microflocules first and later in agglomerates called floccules.

The physical-chemical treatment of wastewater – by adding coagulant and flocculant – is aimed to altering the physical condition of these colloid substances that could remain stable indefinitely to convert them into particles subject to flotation/decantacion by division.

In the video we see that for breaking the stability of colloid particles and separate them easily we carry out three phases: Coagulation, Flocculation and Floating/Decantation.

Succesfull project, installation and commissioning of a WWTP in a dayri industry by Aguambiente

on 26/02/2019 No comments

WWTP Dayri industry 500 m3/day in Palencia (Spain).

The turnkey project is designed for the treatment of 500 m3 / day, although it has been dimensioned with a view to a future expansion of water treatment flow to 600 m3 / day.

The building which home the equipments has been built at two heights in laminated prefabricated panels, mainataining the aesthetics and archetexture to the factory.

The Wastewater treatment plant consists of a pretreatment with rotary screen, which will eliminate part of the solids 0.50 mm, W-Tank® homogenization tank from which the water is pumped to a physical-chemical treatment by dissolved air flotation technology. The process ends with a SBR biological treatment in W-Tank® to reduce the load to the permissible levels of dumping.

The management opted for this type of tanks for its simplicity and speed in assembly. Biological treatment was necessary to reduce the load to the permissible levels of discharge to the public channel.

The dissolved air flotation unit has capacity of 30 m3/ h. The sludge generated in this process of wastewater treatment will be dehydration by an Automatic Press Filter, with which the dryness increase, make easy its management.

After the start up of the treatment plant, Aguambiente’s maintenance team offers training sessions to the customer on “best practices for the operation of the WWTP”. The training is aimed at the personnel who will operate the plant in order to maximize performance and help reduce operating costs.

World Water Day 2018: Nature-based solutions for water

on 22/03/2018 No comments

Every year, we celebrate the World Water Day on 22nd of March to focus on the importance of water as a fundamental component in sustainable development

“The answer is in nature” is the theme chosen for this year. How nature can help us overcome the rising challenges of XXI century. In previous years, themes were related to waste water (2017), employment (2016), sustainable development (2015) or energy (2014). However, in this edition it needs to raise awareness in order to take care of the ecosystems and the nature and how it can create synergies to contribute to Sustainable Development Goals of 2030.

This way, there are many aspects of sustainable development which can be improved by the union of nature and water: from ensuring food security and reducing disaster risk to building sustainable urban settlements and boosting decent work. Nevertheless, there is still a lot to do. In 21st century, more than 2 billion people lack access to safe drinking water and more than the double of that number lack access to safe sanitation

In addition, the demand for potable water is expected to increase more than 30% in 2050. Accelerated consumption patterns, environmental degradation and climate change reveal the need of a mentality change that involves all figures in the society.

The demographic growth that the planet is suffering is also reflected in world water demand’s increase. Both industrial and domestic demand have experienced an increase linked mainly to the growth of emerging countries. And this trend will continue raising at the same rate of their population growth and economic development.

At the same time, climate change is exacerbating environmental conditions in different climates. Drier regions will become more and more arid and wet regions also will turn into more wet places.

Nowadays, 1800 million people live in areas affected by desertification and it is expected that this phenomen will cause more than 135 millions of migrations. Current trend of inundations will continue growing too. Around 1200 million people who live in risk flood areas will become more than 1800 millions in next 30 years.

Fortunately, the attention given to Nature-based solutions has increased for last years. The introduction on these natural solutions in the field of legislation -specially in water resources-, food safety, agriculture, biodiversity, natural disaster risk reduction… has collaborated to be recognized from many sector. Goals the 2030 Agenda for Sustainable Development can lead the way to revers the current trend.

Aguambiente, specialized experts in water treatment, has been treated all kinds of industrial waste water since 1990

Aguambiente is constantly working in the study of new processes which improve the performance of the WWTP (waste water treatment plants) and the cost saving in water management. Years and experience have generated in-depth knowledge in different fabrication processes in many industries and a way to build containerized plants. This way to build compact waster water treatment plants break the mold of megalithic plants and take account of lead time, space and people who daily work there.

What are the most typical client requests when they are going to install a WWTP?

Customer wants to save: chemists saving, energy saving, few residues generated and low maintenance. Twenty four-hour availability to solve possible breakdowns is also important. Treatment process has to be made in little space. This is why we we work with modular plants assembled inside ship containers that can pile up on others.

How does this idea of containerized WWTP arise?

Firstly, we try to optimize lead time and reduce the space. Spanish industry performs its activity in industrial parks where they have not to much available space. Then, manufacture processes are standardized to reduce cost of production. This standardization supposes that equipment leave the factory fully mounted and proved so assembly time and tests in destination are enormously reduced. Portability and ease of transport is another key point.

Are this compact solutions requested from abroad?

Of course! The most part of our market is placed in Spain and Portugal but every time there are more customers from foreign countries. A lot of countries from Europe, South America, Central America or East countries are interested in these compact solutions. Low cost, ergonomic design, lead time, and easy installation and set up are essential characteristics to export this compact WWTP.

There are differences between the way of undertaking these projects in other countries and in Spain?

Yes, each country is different. Cultural beliefs in negotiations are points to keep in mind. Water and landfill legislation is different in every country too. We always try to go ahead of these facts and keep us informed to advise the client perfectly in every sector. In conclusion, industries work in a similar manner around the world and the main strength of Aguambiente is the thorough knowledge of each one of these manufacturing processes.

Which industries is Aguambiente specialized in?

Aguambiente is an expert water treatment company and is specialized in a lot of sectors. We have installed WWTP in foodstuff industries all over the world, in meat plants, dairy plants, wineries, canning factories, pastry and bakery factories, fish processing plants, egg processing plants… There are also a lot of references in textile sector, tank cleaning plantschemical and pharmaceutical industries, metallurgical sector, paper factories, wood industries, waste treatment plants or biofuel plants in which GFRP digesters are becoming very usefull. To highlight some of them, we have recently installed sludge anaerobic digestion in a Slaughterhouse WWTP in Portugal. In this plant we have reach an excellent optimization in operating costs and in the own project, allowing, moreover, the re-use of process water.

What advantages does the customer get with your installations?

At the beginning, the main advantage is the optimization of treatment process and the costs reduction that is what customers want when they request to Aguambiente. The space is also important. Containerized solutions can be easily installed and they can make the plant bigger or smaller depending on the customer needs. Specific increases of production or flow used to be common in certain industries. So, versatility and installation time are very important to our customers. The ease of transport and installation, costs reduction coupled with them and reduction of maintenance are great advantages in relation with traditional plants. In addition, WWTP humanization is vital, we try to make them more functional and easy to use for people who work there daily.

On the other hand, customer can outsource the whole project by rent plants for a fee. Cost of the fee can round 1€/ m3 of treated water and it includes every cost of WWTP: analysis of water and industrial process, project, civil work; equipment supply, installation and set up; chemical products, generated sludge management and preventive maintenance. All with guarantee of energy consumption. Optimization is the most important point from economic view.

What are Aguambiente future challenges?

Legislation on landfills will be more and more strict in fines, fees and taxes. Water is not endless and we have to take care. At the same time, optimization projects will be fundamental in industrial wastewater treatment. We will get less costs, less energy, less water and less waste, and everything cheaper.
