  • Waste Water Treatment


As an accredited ISO 9001 Quality Management Qualification holder and water treatment contractor, PPVS offers vital solutions in waste water treatment for all sectors including privateindustrial and commercial properties with over 50 years of experience servicing more than 250 clients across 2,300 sites and counting in the UK.


Our Water Treatment Process

Waste water is treated using a complex portable blast furnace with a slag mineral filtering system that separates water molecules from solid materials and biological matter.


Polymers are used to coagulate any dirt in the water which is then processed into sedimentation tanks. From there the water flows through special filters before being disinfected.


Following the treatment process, the special filters are then cleaned with pressurised jets of water and involve double screening in order to remove excess matter such as biological waste and grit and the whole process can be repeated as necessary.

Waste Water Treatment

Treating water properly is vital and while the process seems simple, it is a logistical challenge that requires special machinery and professionally trained staff. The 4-step process includes:


  1. Coagulation and Flocculation; creates larger molecules called flocs.
  2. Sedimentation; settles flocs into sludge.
  3. Filtration; removes any remaining suspended impurities.
  4. Disinfection; applies chlorine to kill disease-causing microorganisms.


Water treatment can be used to provide clean and safe water to private clients, construction sites and industrial units to name a few, all through specialised water cleaning techniques that can be adapted for almost any property.

    Coagulation and Flocculation

    The raw water is processed with substances such as aluminum sulphate and sometimes with larger molecules called polymers that cause tiny molecules of dirt to stick to each other in a process called coagulation. Coagulation forces the smaller molecules to form into clumps which in turn stick to each other to form larger clumps called flocs. This process is known as flocculation.


    Because the molecules become enlarged, they become heavier which helps with the next stage of the process when flocs pass through to the sediment tanks.

    Following the coagulation and flocculation process, water is processed into sedimentation tanks. Inside these tanks, water is slowly moved which, along with gravity, causes flocs (coagulated particles) to move to the bottom of the tanks and settle, where they form a sludge substance that is then processed to separate storage lagoons.


    Sedimentation enhances the water treatment process by removing any particulates that might remain in the water. Essentially, this process removes the larger contaminants residing in the water before it is ready for filtration.

    Once flocs have been removed during the sedimentation process, water can then be passed through the filters. Blast furnace slag is used as the filtering medium during a percolation process but other materials such as gravel and anthracite are common. Slag is the byproduct of metal smelting, usually iron into steel and can contain metal oxides, silicon dioxide, sulfides and other metals.


    Filtering is important to remove any leftover microscopic impurities in the water that would otherwise go unchecked. This is the final part of the filter process and therefore the last chance to catch any suspended particles.


    Filters are routinely cleaned with high-pressure water and double screening techniques to maximise efficiency and hygiene.

    As a final precaution, microbial contamination is prevented by disinfecting the water once it has been passed through the filter. Chlorine is almost always used since it is an effective eradicator of disease bacteria and microorganisms.


    While adding chlorine to water might sound a little off-putting, it is perfectly safe for human use when below certain levels and when added to drinking water, the levels are low enough so as to be completely tasteless and undetectable.
