WWTP in dairy industry, problems by Meganema perideroedes

on 29/01/2020 No comments

The filamentous bacteria are generally present in the mocrobiological communities of activate sludege of wastewater treatment plants (WWTP) and insutria (WWTP). The excessive growth of these organizsms could cause seriou problems, foaming and bulking, for the operation of the WWTP. Specifically the IWWTP of dairy Industry are very problematic due the high level of soluble COD in the tributaries, In dayry serum IWWTP there was a problme of bluking, caused by the morphotype Nostocoida limícola, which subsequently was identified as Meganema perideroedes using the Fish technique. There was a positive relationship between the deficiency of osygen and the presence of this organism in the activate sludge. Read the full article here.

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.
