One of the latest application for PVA foam cube in wastewater treatment. The aeration tank in the wastewater treatment plant is using PVA foam as a microorganism immobilization carrier. This is because the open pore structure in the PVA sponge has becomes a good bio-holder for growing up microorganism. The porous effect and high porosity […]
Similar to many plastic material, the PVA sponge has shown good chemical resistance performance for most of the chemical. The good chemical resistance is referring to the sponge roller does not has significant impact in product life span. Unfortunately, there are several chemical or acid solution are actually deteriorating the PVA sponge quality, for instance […]
Improve the PVA sponge quality is definitely our goal. Before we are going through the details, we would like to take this opportunity wishing our business partners and customers for a happy and prosperous new year. Meantime, we reveal our new year resolution so that we could align ourselves with our customers’ requirement. As comments […]
In general, PVA sponge properties have show good chemical resistance, however there are still some chemicals which will bring adverse effect to the sponge material. The PVA sponge consider as a plastic polymer which comes with porous structure. The interconnecting open pore structure perhaps exaggerate the flowing of chemical solution. In general, the plastic polymer […]

Comparing the natural black lava stone and the PVA foam cube. Some of the aquarium lover are using lava stone to cultivate the microorganism in the water. This is very similar application by using the PVA foam cube in the wastewater treatment industry. We purposely get a pack of the lava stone from one of […]

Today we are going to talk about PVA sponge visual deficiency. As a PVA sponge supplier, we are seeing many PVA sponge rollers, either our own product or from other suppliers. We would like to take this opportunity to summarize some visual defects on the PVA sponge. Even though PVA sponge comes in various form […]
We have discussed about the PVA sponge water retention ability earlier, and in this article, we want to talk about the water absorption rate. This is the property indicates how fast the water is moving through the PVA sponge. Let us recap what we had concluded so far. We know that the water retention is […]
The water retention rate of a PVA sponge varies from case to case. We have show our reader some study about the wide variation on water retention rate in the article water retention consider as reference spec. Today, we repeat the same test but on the same PVA sponge. The test shows the difference of […]
The PVA foam or PVA sponge is a synthetic foam that develops 50years ago. For the past 10 years, many industries have introduced PVA sponge in their process. Such as the semiconductor industry, medical, household, agriculture and wastewater treatment processes. In DST, we mainly focus on supplying PVA products for industrial used. However, we have […]
We talked about the water retention for the PVA sponge in previous article. Meanwhile we are getting feedback to understand more about the variation of water retention on difference sponge. So in this article, we further reveal about PVA sponge water retention ability and also the factors which affected this parameters. Furthermore, if the water […]
