Unlike domestic Wastewater treatment equipment, factory wastewater features complex components and strict discharge standards, with budget ranging from hundreds of thousands to millions of RMB. Without professional understanding, enterprises are likely to face budget overrun or poorly matched equipment. Based on rich practical experience in the industry, this article analyzes the core factors affecting factory Wastewater treatment equipment budgets, providing professional references for enterprises to make accurate budget planning.
I. Treatment Scale: Core Basis for Budget Classification
Treatment scale directly determines equipment specification, consumable consumption and process complexity, serving as the fundamental basis of budget planning with cost rising in a stepped trend.
Small factories (5–10 tons daily capacity) mainly treat a small amount of production and domestic Wastewater. Integrated simple treatment equipment can meet demands with a budget generally ranging from 30,000 to 150,000 RMB. Equipped with basic filtration and biochemical units, it fits small processing and light industry.
Medium factories (50–200 tons daily capacity) generate larger Wastewater discharge and require complete pretreatment and biochemical systems with upgraded tank, pump and valve specifications. The budget ranges from 200,000 to 1,000,000 RMB, commonly adopted by food processing and small chemical enterprises.
Large factories and industrial parks (over 500 tons daily capacity) need customized solutions including advanced treatment and reuse systems, with budgets reaching millions. For instance, the Wastewater treatment equipment procurement budget of a chemical industrial park amounted to 23.3775 million RMB, mainly used for high-concentration chemical wastewater treatment.

II. Water Quality & Discharge Standard: Key Variables Causing Budget Differences
The complexity of factory wastewater directly determines the treatment process and further affects the overall budget. Ordinary domestic Wastewater and light production wastewater (such as cleaning Wastewater in general manufacturing) have simple compositions and can be treated by basic processes such as A/O and A²/O with relatively low equipment cost.
Wastewater from food and breeding industries contains large amounts of grease and organic matter, requiring additional pretreatment units such as air flotation machines, increasing the budget by 30%–80% compared with standard equipment. Electroplating and chemical wastewater containing heavy metals and high-concentration organics need special processes including chemical precipitation, ion exchange and membrane separation, pushing the budget up by 100%–200%.
Meanwhile, higher discharge standards mean larger investment. Basic equipment only meeting Grade 3 discharge standards costs less; if Grade 1A discharge or water reuse is required, advanced units such as MBR membrane and reverse osmosis must be added, raising the budget by 50%–100%. For example, a 500-ton-per-day food wastewater project requires a budget of 3–5 million RMB to reach Grade 1 discharge standard.

III. Equipment Material & Intelligence: Important Means of Budget Optimization
Material selection balances practicality and economy, directly affecting budget and service life.
Carbon steel anti-corrosion equipment offers the best cost performance with a service life of 8–10 years, ideal for factories with mild water quality and limited budget, becoming the first choice for small and medium-sized enterprises.
304/316 stainless steel features strong corrosion resistance and aging resistance with a lifespan over 15 years, suitable for chemical and electroplating factories with acid and alkaline wastewater, costing 20%–50% higher than carbon steel.
Fiberglass is lightweight and acid-alkali resistant, priced between carbon steel and stainless steel, perfect for special water quality scenarios.
In addition, intelligence level also influences the budget. Manual control equipment is the lowest in price; PLC fully automatic remote monitoring system realizes automatic equipment startup/shutdown and water quality monitoring. Although it brings a 15%–30% premium, it reduces manual operation and maintenance costs and delivers better long-term economy. For a 500-ton-per-day food wastewater project, a supporting PLC system can save 1–2 operation staff and cut long-term operating expenses.
In summary, the budget planning of factory Wastewater treatment equipment requires comprehensive consideration of treatment scale, water quality standard, material selection and intelligent demand. Avoid blindly pursuing low price or excessive configuration.
Enterprises should first conduct water quality testing and wastewater discharge measurement, clarify core demands, and allocate budget reasonably according to industry market conditions, achieving the optimal balance between environmental investment and treatment effect, meeting compliance requirements while avoiding capital waste.
