components , than for potable water . The Chevron Kern River project , for example , had to operate to the following specifications :
• Flow : 33.5 mgd ( daily maximum )
• Boron : 1.3 mg / L ( annual average )
• Chloride : 200 mg / L ( annual average )
• Electrical conductivity : 940 umhos / cm ( annual average )
• Oil and grease : 35 mg / L ( daily maximum )
• Sodium : 142 mg / L ( annual average )
Most remaining solids and hydrocarbons need to be eliminated , while suspended and dissolved components such as potassium chloride and sodium chloride need to be down to the two- or three-ppm range . Certain state-regulated components will also need to be removed , including , but not limited to iron , chromium nickel and boron . Traditional produced water technologies have a major role to play . Corrugated plate interceptors , induced gas floatation units , nutshell filters , and polishing filters to capture any residual solids create a fairly standard method for treating water
‘ ProSep has provided preliminary front-end engineering and design concepts for several California reuse applications , many of which require the oil and solids to be removed – followed by specific contaminant removal treatment – in order to achieve the standards required for agricultural use ’
