FAQ

What is "Limestone Powder Dosing for Desal. Construction 500L/h 1yr" and what is it used for?

This is a limestone (calcium carbonate) powder dosing system sized for applications with process flows up to about 500 L/h, and it includes a one‑year warranty. It is used to remineralize and buffer desalinated or low‑alkalinity water, stabilize pH, add calcium hardness, and reduce corrosion risk in distribution or process water. Typical application scenarios include post‑RO (reverse osmosis) potable water treatment, construction site water (concrete mixing, curing, dust suppression), irrigation, and neutralization or conditioning of treated effluents.

How does limestone dosing work and which water quality parameters should I monitor?

Limestone dissolves slowly to release calcium and carbonate, which raises alkalinity and buffers pH. The dosing system introduces a controlled limestone slurry (or metered powder feed) into the treated water stream; the reaction and contact time determine final water chemistry. Monitor pH, alkalinity (total alkalinity or HCO3-), calcium hardness, conductivity, and flow rate. Use these readings to adjust the dosing rate to meet target water quality (for example, target pH and alkalinity for potable or construction use).

Where in a desalination train should limestone dosing be installed and is it safe for RO membranes?

Limestone dosing is intended as a post‑treatment step after RO or other desalination units — not before — because solid carbonate in feedwater will promote scaling and foul membranes. Used downstream, limestone remineralizes the permeate and protects distribution systems. If you need to add alkalinity upstream, select soluble alkaline chemicals specifically designed for RO feedwater conditioning and follow membrane vendor guidance.

How do I prepare and feed limestone powder — any recommended practices?

Best practice is to prepare a well‑mixed slurry in a dedicated mixing tank using clean (dechlorinated if required) water and continuous agitation to prevent settling. Typical slurry solids concentrations vary with equipment but often range from low single digits up to ~10–20% w/w depending on the system — start conservatively and adjust. Use appropriate screening or milling to remove oversized particles, feed with a metering pump or controlled screw feeder, keep lines flushed, and avoid dry dust feeding. Always follow the product manual for exact mixing ratios and pump settings.

What routine maintenance is required and what does the 1‑year warranty cover?

Routine maintenance includes inspecting and cleaning the mixing tank, agitator and slurry lines, checking metering pumps and seals, clearing nozzles and strainers, and verifying dosing accuracy with periodic water tests. Frequency depends on use but expect weekly visual checks and monthly functional inspections. The stated one‑year warranty typically covers manufacturing defects in the dosing unit; consumables (pumps, seals, filters) and wear items are usually excluded — consult the warranty terms for exact coverage and recommended spare parts.

Are there safety, storage, or environmental precautions I should follow?

Limestone powder is low‑hazard but produces dust that can irritate eyes and respiratory tract. Use PPE (dust mask/respirator, safety goggles, gloves) when handling dry powder, and ensure good ventilation. Store powder in a dry, cool, sealed area to prevent caking and contamination. Avoid uncontrolled release of slurry to surface waters because changes in pH and alkalinity can affect aquatic life; dispose of residues per local regulations. Follow the supplied safety data sheet (SDS) for full handling and emergency procedures.
