Test Conditions: test solution of NaCl 500 mg/l, P=0,69 MPa, T=25°C , pH=7,5. Recovery – 15%
Nominal rejection is reached after 48 hours of continuous operation on test solution.
Minimal rejection of a new element after 20 minutes test on test solution.

Operating conditions and technical data for designing:

Maximum operation pressure, MPa			4,1/2,1
Maximum pressure drop, MPa			0 ,07
Operation temperature, 0 c 11			4-45
pH at continuous operation at T<35°C			2-11
pH at continuous operation at T<45°C			3-10,5
Chemical cleaning, temperature, °C* ***	T<45	T<35	T<25
CIP pH (short time operation)	2-11	1-13	1-13
Free chlorine content, mg/I max			0,1
Maximum feed flow, m3/hr		17 (KCH 8040-C (F)) 3.6 (KCH 4040-C (F))
Concentrate/permeate ratio on each element, min			5:1
SDI (15 minutes test), max			5
Turbidity, NTU max			1

During continuous work with pH over 10,5 the temperature must not exceed 35°С 2) Flow of each element in a batch may vary +/-15% *In case of chemical cleaning with a solution pH exceeding 11,5 or at the temperature level more than 45°С please contact original manufacturer for consultation.
