Jingxi Daxinan Manganese Production Wastewater Treatment Turnkey Equipment Project
Project Overview
Jingxi Daxinan Manganese is mainly engaged in manganese ore smelting and processing. Its production wastewater is complex, with high levels of heavy metals, salts, and suspended solids, requiring stable effluent quality. Huachuang won the bid and supplied a custom two-stage reverse osmosis (RO) turnkey water treatment system, taking full responsibility for custom manufacturing, transport, on-site installation and commissioning, acceptance testing, and equipment warranty — a one-stop, full-process service ensuring efficient startup and stable long-term operation.

Process Overview The project adopts a mature multi-media sand filtration pretreatment + two-stage RO process, integrated with automatic dosing, online chemical cleaning (CIP), complete water supply/drainage units, and a centralized electrical control system. The skid-mounted, all-in-one design enables fully automatic water production, intelligent flushing, and automatic dosing, suiting the continuous water treatment needs of industrial enterprises. |
Key Technical Highlights
（1）Proven two-stage RO process for stable effluent quality
Sand filtration pretreatment plus anti-fouling two-stage RO membranes create multi-level filtration barriers that progressively remove suspended solids, heavy metals, and dissolved salts. The system delivers strong shock and fouling resistance, adapting to variable raw water quality while steadily producing qualified process water for long-term operation.
（2）Integrated skid design — compact footprint, short construction period
The pretreatment, first-stage RO, and second-stage RO units are modularly integrated, fully prefabricated, assembled, and tested at the factory. On-site, only leveling, piping connection, and utility hook-up are required, greatly shortening installation and commissioning time and saving floor space — ideal for compact industrial sites.
（3）Fully intelligent automation — easy O&M, low cost
A centralized PLC system integrates automatic water production, timed flushing, automatic dosing, level interlocking, pressure protection, and fault alarms, with pneumatic valves enabling fully automatic pipeline switching. The system runs without frequent manual intervention, cutting labor costs and ensuring safe, stable, low-failure operation suited to continuous, unattended industrial scenarios.
