Planning and implementation of an upgrade to the pre-treatment system for sewage, carrying wastewater from the Ma’adanei-Mizra food factory. The construction of the system was preceded by a thorough examination of the production processes, in order to allow discharge of the wastewater into the main public sewage system, in accordance with Industrial Waste Regulations.
Sewage from food production facilities contains a high mass of different oils, and therefore needs to go through a pre-treatment system before it can be sent to the main sewage system.
