The Discharge Of Effluent Has Become Increasingly Expensive.

• Even efficient cleaning often produces a large volumes of caustic effluent.
  It is now possible to recover more than 90% of a spent caustic solution by using a mixture of pH resistant nanofiltration membranes and sensible CIP programming.
  

• Cooling water that has been in contact with food products is often discarded in the belief that it is "too" contaminated for re-use.
  Membrane filtration was introduced to the food industry almost 30 years ago. Sterile filtration, protein concentration, dewatering and desalination are typical membrane processes which individually or in combinations find their use in the manufacture of liquid foods. It is a simple step to use these techniques to treat the waste waters produced in the food industry.
  

• CIP systems have been overlooked many times in the automation age because of their reliability.
  In many cases, this can be misleading because the system installed as little as 5 years ago may not be utilising the full potential of today’s technologies. Many of these enhancements can be added to your PLC based CIP system.
  If your system is not PLC based, there may be many opportunities to greatly improve the systems performance. In some facilities a 50% decrease in water usage have been realised along with similar reductions in effluent discharges.
  Chemical, heating and electrical costs can also be decreased with optimisation of the process
  

• Secondary uses for contaminated waste water.
  In many situations a secondary use can be found for process waters that are normally considered as waste. With suitable filtering and disinfection process waters can often be reused in cooling / heating systems.
