Pollution Control has recently designed, manufactured and installed a complete dissolved air flotation (DAF) based system to treat the effluent from a new mayonnaise factory.
The DAF module was part of a complete effluent plant that included mixers, tanks, dosing and gross solids screening, all controlled by a PLC controller.
Pollution Control recently installed three more groundhog model 1200 slurry separators to add to the impressive list of separators working successfully on sand-laden slurry. In addition, the simple design principle requires very little maintenance, ensuring minimum parts come in contact with the slurry so there is no costly rebuild.
Working countrywide, the installations were in Cornwall, Hampshire & Monmouthshire.
Pollution Control has recently exported three LC50 lamella clarifiers, chemical dosing systems and pipe flocculators to New Zealand. The clarifiers will be used in the growing rental sector to filter silts and solids from groundwater construction sites.
The remit was to supply lamella clarifiers that could be quickly and easily installed on-site with minimum installation.
Pollution Control designed a skid-based system with a collapsible safety handrail and access ladder system. This would allow the clarifier to be easily loaded, transported, and fully operational shortly after arrival at the site.
Due to the shipping cost, the clarifiers were designed to fit inside a high-cube shipping container. Owing to the rigours of the rental market, a full two-pack protective paint system was applied both externally and internally. This will provide the client with years of service with minimum maintenance.

Pollution Control has recently supplied a bespoke containerised eco-n-saf system to treat all the wastewater at the British Embassy in Kabul, Afghanistan.
The technical works manager at the Embassy requested that the system be an above-ground modular containerised design. This is because the sewage treatment plant must treat a maximum flow of 35m³ daily. It also must be easy to install and movable for rapid de-commissioning & re-commissioning.
The wastewater comprises on-site accommodation (toilets, showers, etc.) and laundry. In addition, the treated effluent was to be used for irrigation.
All sewage is held in a cesspit and periodically removed off-site by a tanker.
The new containerised system included a primary/balance chamber, three eco-saf bio cells, a lamella clarifier and an integral controls room. The bespoke design includes solids reduction, bod reduction and final lamella clarification with a reduction of total-n.
The containerised system was supplied to iso shipping container dimensions c/w ISO container locking mechanism. Due to the harsh transport and site conditions, a full high-quality two-pack protective paint system was applied internally and externally.
Due to the difficulty of sending engineers to Kabul for the installation & commissioning, all external connections were simplified to ensure a true ‘plug & play’ system.
The on-site engineer spent time at our facility for training and visited a local site with one of our engineers to experience the service and maintenance of a similar system.
Pollution Control has recently installed a complete above-ground Eco-n-Saf modular system. This is to treat the wastewater from a new luxury sustainable home holiday village.
As the new village is in the Poole Harbour catchment area, it is subject to strict regulations from Natural England and the environment agency regarding exporting Nitrogen compounds from the development.
The client originally looked at buried systems, but after a visit to an above-ground Eco-Saf installation that Pollution Control installed for the building phase of the new Carrington power plant (treating the wastewater from up to 1000 site staff). He was sold on the benefits in both ease of maintenance of the system and the overall cost.
The bespoke design is part of the site’s complete nutrient management plan. Therefore, this includes solids reduction, bod reduction, lamella clarification and exceptionally high reduction of total-n and total-p.
Once the treated wastewater has passed through the wetland treatment system, it is expected to be nutrient-neutral.
A specialist welding procedure to BS EN 15614-5 has been developed and approved for welding Zirconium tube endcaps. When the tubes are filled with Boron Carbide pellets, they are used as neutron-absorbing rods in the nuclear fuel industry.
Welder approval to BS EN ISO 9696-5 has been attained. This was a particularly delicate welding procedure as the tubes only measured 9.5mm in diameter with a wall thickness of 1.
Pollution Control has recently installed two Groundhog separators to add to the list of trouble-free separators working on sand-laden slurry. They have replaced screw press-type separators (one in Dorset and one in Cheshire). The customers found that although screw presses initially worked well, after changing their bedding regime to sand, excessive wear was noticeable, making them an expensive machine to keep in service.
Existing support steelwork was modified, and both separators now require minimum maintenance.
Pollution Control has also developed a Groundhog sand washing and dewatering process to reclaim 75% – 85% of sand bedding. The equipment uses hardened steel parts to provide minimum service requirements.
All Pollution Control welders have successfully undergone testing for welder approval to the new welding standards BS EN 9606-1.
This new standard has replaced BS EN-287-§. Any welder approval to BS EN 287-1 is valid until October 2017.
Pollution Control recently underwent a rigorous quality audit which is a requirement to remain a prefered supplier to the nuclear fuel manufacturer Springfields fuels ltd (a Westinghouse company)
The audit ensured that Pollution Control could continue as a preferred supplier of over 40 years of service to the nuclear industry.
