Is polyaluminum chloride a good coagulant?

Polyaluminum chloride (PAC), which is widely used as a versatile coagulant in drinking water supply plants , is considered useful in treating microalgae-laden water because of its high economic efficiency and microalgae removal effects.

Does polyaluminum chloride (PAC) contain fulvic-like acids and humic-like ketones?

The characterization was performed under different alkalinities and dosage treatments of polyaluminum chloride (PAC). Results suggested fulvic-like and humic-like acids, C C, and unsaturated aldehyde ketones were present in the supernatant liquor and dissolved EOM (dEOM) solution under logarithmic and stationary phase treatments for EOM.

Should microalgae-laden water be treated with Pac 2.0 alkalinity coagulation?

Thus, treating microalgae-laden water at the stationary growth phase with PAC 2.0 alkalinity coagulation with 50 mg L −1 dosage treatment is a good approach. The novelty and originality is justified by highlighting that the manuscript contains sufficient contributions to the new body of knowledge of microalgae coagulation.

Can aluminum salts cause microalgae cell damage?

This was agreed with the result of Papazi et al., which indicated that aluminum salts could cause microalgae cell damage . In these three phases, there no obvious difference in microcystin concentration was found between original microalgal treatments and the supernatant liquor of the PAC treatments.

How to treat microalgae-laden water at a stationary growth phase?

The microcystin concentrations under logarithmic and stationary phases were significantly lower (P < 0.05) than that under the decline phase. Thus, treating microalgae-laden water at the stationary growth phase with PAC 2.0 alkalinity coagulation with 50 mg L −1 dosage treatment is a good approach.

Which coagulation pH should be used to treat microalgae laden water?

Therefore, coagulation pH of 2.0 and 50 mg L −1 dose of PAC was a good practical application to treat microalgae laden water at the stationary growth phase. 1. Introduction In recent years, harmful microalgal blooms have occurred at increasing frequency and intensity in various water bodies, such as shallow lakes and reservoirs.
