Sewage treatment equipment procurement is an important part of environmental protection projects, but there are many pitfalls in the procurement process. How to avoid pitfalls? The following guide will help you make efficient decisions!
1. Accurate demand analysis
Clarify the type of sewage (chemical wastewater/domestic sewage), daily treatment volume, emission standards (such as COD, ammonia nitrogen limits), and analyze the range of water quality fluctuations. Avoid blindly choosing "low-priced general models" that lead to substandard treatment or repeated investment. It is recommended to entrust a third party to test water quality and customize process solutions.
2. Strictly review supplier qualifications
Verify whether the company has the "Environmental Protection Equipment Production License" and ISO quality certification, and confirm the practicality of patented technologies (such as membrane treatment and anaerobic reactors). Be wary of "OEM factories" and give priority to independent research and development capabilities.
3. Field verification cases
Require suppliers to provide cases of similar projects in the past three years, and conduct field inspections of equipment operation stability (such as failure rate), energy consumption (ton of water and electricity consumption) and sludge treatment costs. Focus on the treatment effect under high load.
4. Contract risk prevention and control
In addition to the warranty period, it is necessary to clarify the acceptance standards (such as 30 consecutive days of standard emissions), accessories price list and technology upgrade terms to avoid hidden charges.
5. Full life cycle cost accounting
When comparing equipment prices, it is necessary to comprehensively calculate the 10-year operation and maintenance costs (electricity, chemicals, and labor). For example: although high-efficiency aerators are expensive, the long-term energy-saving benefits can cover the initial investment.
6. Digital service capabilities
Prefer smart equipment suppliers that support remote monitoring, fault warning, and data tracing to reduce manual inspection costs and improve the efficiency of responding to emergencies.
