BP-6010 & BP6010CH: Overview
GX1000: w/ Auto Shut-Off Valves & Float Valves
KDF= KDF85/Catalytic Carbon Filter. KDF85 Bacteriostatic media controls the growth of microorganisms. Good for water-soluble metals removal, chlorine, chloramine, and scale. Highly reactive catalytic carbon, extremely porous and long-lasting. Absolutely the best carbon filter available, a must for well water treatment, and the best option for removal of CHLORAMINE! Needs flushing upon initial startup and after filter changes to remove carbon fines and dust.
CC= White Coconut Carbon Block. Ultra high purity coconut shell activated carbon filter. Superior chemical absorption and turbidity reduction. The unbeatable cost of performance value.
GB = Green Coconut Carbon Block. NFS61 listed carbon filter manufactured with a patented process that greatly reduces greenhouse emissions—High flow with a low carbon footprint and superior chlorine removal.
SP = Spun polypropylene - A true multi-staged depth filter utilizing separate layers of micron filtration. Constructed spun polypropylene, these filters offer superior dirt holding capacity at an extremely economical price. They have more pressure drop than pleated filters. Great filter for changing frequently, especially in well water applications, or any situation where feed water is loaded with sediment.
PL = High flow pleated sediment filter: This is a washable, reusable, and durable sediment filter with a very low-pressure drop. Bacteria and chemical resistant. Great for high flow applications and extended time between filter changes.
HF = High Flow Cold Water Membrane element. Less rejection than high rejection membranes, but with a much higher flow rate. Superior flow in cold water conditions as well. Our most popular membrane element.
HR = High Rejection Membrane element. More rejection than high flow membranes, but with less flow rate. Great for ultra pure drinking water.
Q: How does water temperature effect flow rates through RO filters?
A: Between 77° and 50° water system production declines by 50%, as cold water is more dense, more viscous, and more difficult to move through the membranes.
Q: What can be done to combat the effects of cold water on RO membranes?
A: Increasing the water pressure with a booster pump. Increasing the feed water temperature, which some people do by mixing warm and cold water from a diverter valve.
Q: Does the system ratio (waste ratio) change over time?
A: System ratios can change over time if the flow restrictor starts clogging due to hard feed water conditions.
Q: Does the system ratio change with water temperature?
A: System ratios (waste ratios) can drift with cold feed water. Water travels the path of least resistance — the drain line! It’s important to check the system ratio during the winter months and adjust if necessary.
Q: How can the system ratio be adjusted?
A: System ratios can be tuned with a ball valve or Flow Box. Never go lower than the system was intended for.
Q: How much water pressure is needed to run an RO system properly?
A: RO membranes require 40 psi of incoming pressure to produce even a drop of water except for our GXM200-HF which requires only 20PSI. The only membrane on the planet that can do this.
Q: What’s the maximum feed water pressure that an RO system should run on?
A: Incoming feed water pressure on all water filters, always and everywhere, should be no more than 80psi. Plastic filter housings cannot handle more pressure.
Q: Can all GrowoniX water filters be used with well water?
A: Well water is generally too dirty for small RO membranes (100GPD through 400GPD systems). The large 4” membranes of the bigger systems (600GPD and larger) are recommended for well water treatment unless the water demand is really low.
Q: Are there any special filters needed to treat well water?
A: KDF85/ catalytic carbon filters are a must for well water treatment. This premium catalytic carbon filter with a bed of KDF85 media can reduce iron, hydrogen sulfide, heavy metals, and bacteria—all things that wreak havoc on RO components—, especially membranes. Other consideration for special filters can only be deduced with a laboratory water analysis.
Q: Does GrowoniX help with well water analysis?
A: We do. Just send us your water analysis and we’ll look at it for free. If you don’t have a recent analysis, you can either use a local water lab or purchase a test kit through GrowoniX send it off to our partner lab.
