Extreme,Numbers! to double production on a 200GPD yoy will need to add 2 membranes.steve@freshwatersystems.co.uk
john,production rate is a combination of several factor, the water quality, the water temperature, the water pressure and the membrane type/quality. Just because you get 288 litres per day at 65psi doesn’t mean every one else will. eg if I run one of our 100gpd membranes on our water (5'C 280ppm hard) I get 1 litre every 4 mins 40 secs = to 308 litres a day and the product water is at 8ppm that about 97% reduction. Even at similar pressures you get different results in different parts of the country.steve@freshwatersystems.co.uk
