What does a preliminary analysis of wastewater discharge involve?

on 25/05/2020 No comments

In order to assess the issues presented by each discharge, we must understand its composition via sampling. This involves analysing the most representative parameters and performing tests such as the Jar test to ascertain process performance, allowing us to select the best treatment for each specific case.

Preliminary analysis of wastewater discharge allows the pollutant load discharged by a company to be analysed and the treatment best suited to each company to be identified.

To ensure a correct analysis of wastewater discharge, an automatic sampling device must be used to allow samples to be taken on a regular basis 24 hours a day. It is also important to establish whether there are any specific times when the factory discharges more wastewater than usual, leading to a temporary increase in load and flow.

Once the data has been collected, the samples are sent to the laboratory. Tests are carried out on all parameters (QDO, QBO5, MSS, NT, P, K, heavy metals, pH, conductivity, temperature, etc.) considered necessary to inform the design of the purification system.

World Water Day 2020: Water and climate change

on 11/03/2020 No comments

Since 1993, World Water Day has been celebrated every year on 22 March. World Water Day 2020 focuses on water and climate change, and on the close link between the two issues. The campaign shows that, depending on our use of water, we can reduce floods and droughts, combat the scarcity of that resource and its pollution, and at the same time help combat climate change itself.

This campaign contains three key messages:

We can’t afford to wait. Water should be a priority in climate action plans.

Water, a resource against climate change. Sustainable, affordable and adaptable solutions in water and sanitation.

We can all be an active part. In our daily lives, various surprisingly simple actions allow us to fight climate change.

It is incredible how many water-related actions anyone can implement anywhere to fight climate change. Some changes of habits that we can all put into practice today:

Take five-minute showers

More plant-based meals

Do not throw away food in good condition

Turning off electronic devices

Buy sustainably.

The aspiration to reach even the most vulnerable is becoming increasingly important, as environmental degradation, climate change, population growth and rapid urbanization, among other factors, intensify and pose considerable challenges for water safety.

However, water and sanitation can contribute significantly to the achievement of the comprehensive set of 2030 Agenda for Sustainable Development objectives, ranging from food and energy security to economic development to sustainability Environmental.

Climate change largely serves to give a necessary impetus to the implementation of obvious reforms in the water sector.

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.

Aguambiente completes the execution of the filtering and sludge line for hydrocarbon waters plant in Malta.

on 15/07/2019 No comments

Aguambiente has completed the installation of a water and sludge treatment system in Malta for a hydrocarbon water plant from ships.

The project has been carried out with pre-assembled equipment in a container, so that it is easier to install and assemble it on site. This reduces the execution of civil works.

The installation has been arranged in three containers and consists of:

A first container for the filtering line includes:

– Sand filter for 10 m3 / h with water and air washing with blower.

– 2 ud active carbon filters of 2,400 liters capacity for a flow of 5-10 m3 / h. These may work in series or in parallel.

Another sludge dewatering line formed by two containers that include:

– Muddy tank with agitation 6,000-liters.

– Dosage of chemicals: Coagulant and emulsified flocculant.

– Automatic Polyelectrolite Preparation Plant.

– Pumping of sludge.

– Draco® FPA 80/20 Automatic Filter Press.

– Filtered water pumping tank 1,000 liters.

 

The containers that have been installed are equipped with:

– Connection between equipment

– Conditioning of walls and floors, sandwich panel

– Interior lighting and power take-off.

– Helical fan with ventilation grid.

– Air Conditioner.

– Security elements, fire extinguisher, first aid kit.

– Anti-slip floor made of silica sand with GRP.

– Internal drains.

– Access pedestrian door.

The project also includes a Defender® FSH5 hydrocarbon separator, where the separation process is carried out in two phases: water phase and oil phase. The separation process is based on the effect of coalescence, increased by lamellar and stable flow conditions, by passing the effluent through the package of lamella coalescing pack.

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.
