The phrase "a two step treatment" is correct and usable in written English.
It can be used when describing a process or method that involves two distinct phases or actions for treatment purposes.
Example: "The doctor recommended a two step treatment to effectively address the patient's condition."
Alternatives: "a dual phase treatment" or "a two-part treatment".
Eligible and consenting participants are randomised with equal probability to either a minimal intervention or a three step treatment approach.
High power conversion efficiency values of 6.01% and 4.57% were obtained for devices based on K2 PC71BM and K3 PC71BM active layers with optimized donor to acceptor weight ratios and processed with a two step annealing treatment.
We tested the long-term As removal efficiency of a two steps ZVI treatment unit for the production of 400 L/day clean water based on the combination of ZVI corrosion process with sedimentation and retention of freshly formed Fe precipitates.
The maleimide groups were grafted on an untreated T700 carbon fiber from a three step surface treatment: (i) nitric acid oxidization, (ii) tetraethylenepentamine amination, and (iii) bismaleimide grafting.
Starch removal to obtain dietary fibers is usually accomplished via a three step, sequential enzymatic treatment procedure using a heat stable α-amylase, protease, and amyloglucosidase.
The present research explores the application of glucose obtained from acid hydrolysis of the seed cake for ethanol production in a three step process: acid treatment, neutralization and fermentation.
A cluster-randomized clinical trial, the Mobile Diabetes Intervention Study, randomly assigned 26 primary care practices to one of three stepped treatment groups or a control group (usual care).
The deposition of platinum on silicon and titanium carbide based CDC was studied, using a three step process of acid treatment, ion-adsorption of platinum precursor and gas phase reduction.
The β-segregation is removed effectively after the first two step heat treatment, a short-time holding within β single phase field then annealing in α+β phase field.
As a conclusion, the water produced by two step NF treatment of biologically treated pulp and paper industry meets the quality of actual process water.
In this work, Co3O4 nanoparticles (NPs) encapsulated in a well-aligned carbon nanowire array on a 3D Ni-foam is successfully designed and fabricated by using the Co2(OH)2(CO3)2 nanowires as templates and followed by surface glucose polymerization and two step annealing treatment.
