The worst thing about manufacturing wastewater treatment equipment is when customers come to me with two quotes, asking, "This one is 40.000 yuan cheaper than yours, am I overpaying?" Frankly, if you only look at the numbers on the quote, you're bound to be ripped off by unscrupulous vendors. Today, I'll share some common low-price tricks used by wastewater treatment equipment manufacturers.
Wastewater Treatment Equipment
The difference between the quoted price and the actual cost
The price you see for wastewater treatment equipment is just the tip of the iceberg. Wastewater treatment equipment manufacturers quote low prices by cutting out essential components. They don't include automatic dosing systems, online monitoring, or pipe materials. Once you sign the contract and installation begins, they'll add extra charges for this and that, resulting in a higher total price than others. Let me tell you, I've seen this trick at least fifty times. At DIEN Water Treatment, we don't do that. What's on the quote is what it is: automatic dosing, online monitoring, 316L piping—everything that's necessary is listed. We don't play those late-night add-on tricks. Our pricing is completely transparent.
A Review of the Price Pitfalls Experienced by a Xi'an Food Factory in 2023
Last year, a food factory in the northern suburbs of Xi'an, with a daily processing capacity of 80 tons, hired a wastewater treatment equipment manufacturer that offered a price 20.000 yuan cheaper. After two months of operation, the effluent COD hovered around 120 mg/L, while the standard was below 100. They called the manufacturer to adjust it, and the manufacturer said adding a carbon source dosing system would solve the problem, quoting 18.000 yuan. See, the equipment was 20.000 yuan cheaper, but the subsequent repairs cost 18.000 yuan, not even including the losses from the few days of shutdown. Later, they contacted our company, DIEN. When I visited the site, I found that the equipment didn't even have sludge return; the biological treatment tank was just for show. The entire replacement cost 120.000 yuan, but now their effluent is consistently below 60 mg/L, and they haven't had any problems for over a year.

What aspects should you consider when buying wastewater treatment equipment in 2026?
First, check if it has automatic dosing; second, check if it has online monitoring and linkage; third, check if the pipe material is 316L stainless steel. If any one of these three components is missing, you'll face a whole host of problems later. Our DIEN reverse osmosis equipment and wastewater treatment equipment are all equipped this way, not because we're particularly noble, but because these are the essential components. If you save money on these, you'll have to pay ten times more to make up for it later.
