Water Purification Technologies

Removing Hazardous Pollutants

Coftec’s range of precision engineered solutions for industrial and municipal water purification applications assists companies in meeting their environmental obligations as well as providing opportunities for process optimisation using cutting-edge technologies.

Reverse Osmosis (RO)

Reverse Osmosis plants are suited to several applications, from sea water desalination, brackish or well water purification for drinking, to industrial applications of various types including feed water for resins for demineralisation, water for thermal power stations, food, chemical, electronic, pharmaceutical plating industries, etc. The reverse osmosis technology also permits, with suitable pre-treatments, the recovery of some types of discharge water.

Ultrafiltration (Uf)

Ultrafiltration can be used to target waterborne bacteria, protozoa and some viruses. Nanofiltration removes these microorganisms, as well as most natural organic matter and some natural minerals. These membrane filtration processes are used when conventional treatment technologies fail.

Membrane technology is also effective at targeting many emerging contaminants including herbicides and pesticides and can play a key role in industrial water recycling.

Adsorption/Oxidation

Nyex is proven to be extremely effective at removing industrial pollutants from wastewater as a polishing step. Nyex is particularly effective at removing pharmaceutical residues such as Active Pharmaceutical Ingredients (APIs) to trace levels, as well as many Endocrine Disrupting Chemicals (EDCs), so it is well placed to help in the battle to reduce Anti-Microbial Resistance (AMR).

As well as the pharmaceutical market, target markets include fine and specialty chemicals, agrochemical, aquaculture as well as the semiconductor industry. Market drivers range from wastewater compliance with regulations, CSR and sustainability targets (reducing incineration) as well as water reuse.

Nyex Technology Benefits

  • No chemical dosing so safe and low-cost operation
  • Produces no secondary waste streams, enabling significant cost and operational savings
  • Extremely effective wastewater polishing step which reduces pollutants to compliance limits
  • Robust treatment which can be switched on/off as needed
  • Modular and scalable

MBR

Membrane Bioreactor (MBR) is a wastewater treatment technology comprising membrane filtration with a biological wastewater treatment process. It is becoming the go-to process of choice for many industrial applications due to its high performance and reliability.

MBBR

Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process based on biofilm formation. The MBBR system consists of an aeration tank (similar to an activated sludge tank) with special plastic carriers that provide a surface where a biofilm can grow. Biofilm processes in general require less space than activated sludge systems because the biomass is more concentrated. Other advantages of our Green MBBR system include:

  • Compact unit designed to the dimensions of standard size shipping containers
  • Pre-treatment, denitrification, biological oxidation with MBBR, sedimentation with lamella pack, sludge recycling
  • MBBR technology reduces plant space requirement
  • Very responsive to load fluctuations
  • Modular so the system can be scaled up or down to cater to different capacity requirements
