Development of Separation Equipment for Sand Laden Slurry
Reputation Of Groundhog Slurry Separators To Deal With Sand Laden Slurry Grows 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.
Welding Qualifications
Welding Qualifications 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.
Successful SO 9001 Quality Audit
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.
Reducing High COD, BOD & S/S Loads In Cheese Processing
Reducing High COD, BOD & S/S Loads In Cheese Processing Designed to treat the effluent on site to acceptable levels for direct discharge to field soakaway Gross solids screened out of the effluent Reduction in COD/BOD of 85% and Suspended solids of 90% Above-ground installation that reduced civil cost and installation time scale Low operation and maintenance cost Project Description F J Needs Ltd WWTP is a bespoke effluent treatment system and is based on our high-performance modular Eco-SAF biological system comprising of: Inlet pump chamber Mechanical brush screen for solids separation Hydraulic flow control Up-flow Bioreactor based on Submerged Aerated Filter (SAF) technology Final clarification in a Lamella Clarifier Flow 4m3/day Average COD 5900mg/l Average BOD 3500mg/l Average S/S 2500mg/l Design flow 0.12l/s The effluent treatment system is to treat the site wastewater to the minimum trade effluent quality as follows: Parameter Unit Discharge standard COD (settled) mg/l < 1000 BOD (5 day settled) mg/l < 500 Suspended solids mg/l < 120 Preliminary treatment: Comprising of the following elements Inlet pump station c/w Duty/Assist set back vortex impellor submersible pumps Mechanical brush screen Secondary Treatment: The Eco-SAF module – the essential biological stage where bacterial microorganisms are cultivated and actively consume the suspended organic material found in the decanted liquid from the primary process. The aerated cells are equipped with a fine-bubble aeration system distributing the oxygen required for a healthy and stable population of heterotrophic bacteria. Oxygen is supplied to the air diffuser system by a side channel blower that requires minimum maintenance. The module is a series of aerated cells and anoxic zones. The aerated cells are also furnished with fully submerged bio-film growth media to ensure that the microorganisms have a substantial area for growth and a stable environment. In addition, full floor coverage with the aeration diffusers ensures maximum oxygen transfer and no ‘unaerated’ dead zones as in circular tank designs. Final Settlement – Clarifier. Any remaining solids (Humus) are settled out of the biologically treated effluent with a lamella pack and returned upstream as enriched activated sludge (RAS) to be absorbed in fresh wastewater. The lamella pack increases the active area and therefore improves the settling ability of the sludge within a small footprint. The Eco-SAF system was selected for the following reasons: Predictable performance Lower operation and maintenance costs No interruption to the process whilst servicing the aeration system Modular design that can be added if production is increased Better whole life cost Easy installation with minimum excavation required Life expectancy of over 30 years with minimum maintenance No internal moving parts Easy to de-sludge Manufactured to Quality Management System ISO 9001 Download the PDF here
