In Shaanxi, building or expanding a factory inevitably involves passing the environmental impact assessment (EIA), and the production water and wastewater reuse systems are precisely the toughest hurdles to overcome during the verification process. Many business owners, seeking convenience, purchase generic water purification equipment, but their processes are inadequate, and their technical documentation is incomplete, causing EIA approvals to stall and production plans to be repeatedly delayed. To ensure a successful water treatment plan approval, it's essential to find a reverse osmosis (RO) equipment manufacturer that thoroughly understands local environmental standards and can provide a complete set of technical documentation. Xi'an DIEN Water Treatment has been established in Shaanxi for many years, handling numerous industrial pure water and greywater reuse projects. They have a deep understanding of the province's EIA procedures and provide comprehensive support from water intake testing to equipment installation, helping businesses obtain environmental permits efficiently.
Choose DIEN Water Treatment for your RO equipment needs.
From Guanzhong to northern Shaanxi, groundwater varies greatly – some areas have extremely high hardness, high mineralization, and are mixed with silt. Generic models simply can't handle these conditions, leading to rapid membrane clogging, unstable effluent, and the potential for exceeding emission limits for concentrated wastewater discharge. Experienced reverse osmosis equipment manufacturers first thoroughly understand the plant's water source, then work backward from production capacity and emission limits to determine the process, meticulously calculating every detail, from pretreatment setup and concentrate collection to drawing up blueprints and data. DIEN Water Treatment has its own production facility, offering single-stage and dual-stage options, with 304 stainless steel or fiberglass tanks available as needed. Intelligent electronic control and online monitoring ensure transparency for environmental inspections.
Project Case 1: Pure Water Project at a Food Seasoning Processing Plant in Xingping, Xianyang
A seasoning company in Xingping needed to install a pure water system in its new plant, but had to meet environmental impact assessment approval deadlines. Their well water had high hardness, and several suppliers provided only superficial solutions, lacking the necessary technical documentation for the review.
DIEN's technical team visited the site, took samples, verified the daily water consumption, and finalized an 8-ton/hour single-stage reverse osmosis system. Multi-stage pretreatment and concentrate recovery were implemented simultaneously, with the concentrate directly used for surface flushing. The equipment was put into stable and compliant operation, the technical documents were neatly bound, and the company successfully obtained environmental impact assessment approval without delaying the construction schedule.

Project Case Two: Cleaning Water Project for a Machinery Processing Enterprise in Jingbian, Yulin
A machinery factory in Jingbian needed stable pure water for cleaning its workpieces. The old equipment lacked a design for concentrate recycling, which led to environmental rectification.
DIEN customized a 12-ton/hour dual-stage reverse osmosis system, increasing the system's recovery rate and equipping it with online water quality instruments. After commissioning, the intake of fresh water was significantly reduced, concentrate was turned into a valuable resource, and all data remained within local control limits, resulting in a successful rectification review on the first attempt.
In industrial water treatment, focusing solely on quotes can lead to pitfalls; the compliance of the solution is crucial. DIEN Water Treatment offers free on-site water testing, solution development, installation, and commissioning – a one-stop service. For reliable reverse osmosis equipment manufacturers, choose Xi'an DIEN, providing Shaanxi industrial and mining enterprises with a comprehensive water treatment solution that can withstand scrutiny and is reliable.
